Nice review:

Despite its unassuming performance in DirectX 9 benchmarks, the ATI Radeon HD 2900 XT is capable of beating the Nvidia GeForce 8800 GTX, which is much more expensive, in DirectX 10 applications provided that the Catalyst driver has game-specific optimizations. Of course, Nvidia’s ForceWare driver has to “know” the particular game to run it at a high speed, too.
The ATI Radeon HD 2600 XT and HD 2400 XT are kind of DirectX 10 kings in their respective price categories. However, these cards often prove to be slower than Nvidia’s GeForce 8 in the more important DirectX 9 applications.
The ATI Radeon HD 2000 architecture features the most advanced implementation of DirectX 10 today.
Performance of both ATI Radeon HD 2000 and Nvidia GeForce 8 is fully dependent on drivers, therefore, it is nearly unpredictable which graphics card will eventually become better DirectX 10 performer.
